[FC7-test1_dvd] setting desktop-effect

[LarryT <gparted gmail com>]

Somethink really fun when i click on the new beautiful menu Control 
Center / select effect : this has the awsome effect to logout  the user. 
'Try it much times and the same comes.

(BTW "Control center" is really nice & ergonomics. And i love the new 
icon for launcher, from menu "+add to panel".)
